(A)Thromboplastin/Thrombokinase → Fibrinogen → Fibrin; Thrombin Prothrombin; → (+ dead and damaged formed elements) → Clot
(B)Thromboplastin/Thrombokinase → Thrombin → Prothrombin; Fibrin Fibrinogen → (+ dead and damaged formed elements) → Clot
(C)Thromboplastin/Thrombokinase → Prothrombin → Thrombin; Fibrinogen Fibrin → (+ dead and damaged formed elements) → Clot
(D)Thromboplastin/Thrombokinase (from injured platelets/tissues) → Prothrombin Thrombin; Fibrinogen Fibrin → Clot (+ dead and damaged formed elements)Correct
Answer: (D)
Solution
The correct clotting cascade is: thromboplastin released from injured tissues/platelets converts prothrombin to thrombin in the presence of , and thrombin then converts fibrinogen into fibrin, whose
